Aims:
To analyze the clinical presentation, histopathological spectrum, diagnostic challenges, and surgical management of parapharyngeal space tumors treated at our institution over a 10-year period.
Methodology:
A retrospective study was conducted on patients diagnosed with parapharyngeal space tumors between 2015and 2025. Clinical records were reviewed for demographic data, presenting symptoms, radiological findings, histopathology, and treatment details. Imaging modalities including contrast-enhanced CT and MRI were used for tumor localization and assessment of relation to surrounding neurovascular structures. Tumors were classified based on tissue of origin and biological behavior (benign or malignant).
Results:
A total of 38 cases were identified. Benign tumors constituted 31 cases (81.6%), while 7 cases (18.4%) were malignant. Salivary gland tumors were the most common (20 cases), of which 15 were benign and 5 malignant. Neurogenic tumors accounted for 16 cases, including schwannoma (8 cases), paraganglioma (5 cases), and neurofibroma (3 cases). Miscellaneous tumors comprised 2 cases, including one synovial sarcoma and one vascular tumor. The most common clinical presentations included neck swelling, oropharyngeal bulge, and dysphagia. Radiological imaging played a key role in preoperative diagnosis and surgical planning. Surgical excision was the primary treatment modality in the majority of cases.
Conclusion:Parapharyngeal space tumors are rare and predominantly benign, with salivary gland and neurogenic tumors forming the majority. Accurate imaging and careful preoperative planning are essential due to the complex anatomy of the parapharyngeal space. Surgical management remains the mainstay of treatment, and awareness of the varied histopathological spectrum helps guide appropriate management strategies.
